Title: Servo circuit
Inventor: KAN TOSHIYA
IPC: H02P25/098
Filed: 1990-01-12
Abstract: PURPOSE:To avoid overshoot and to realize quick rising by comparing the current value of error in the rotational period of a control target with a preceding sample error value multiplied by a predetermined value, and then switching from quick starting acceleration to steady state. CONSTITUTION:A servo object, e.g. a drum motor S, is started and accelerated quickly according to a rising characteristic 34 and then a rotational speed signal FG is provided to a servo circuit 3. A rotational period detecting means 30 in the servo circuit 3 determines the differences TER(i), TER(i-1) between a target rotational period and the rotational periods of current and preceding samples, which are then provided to a judging circuit 31. An operating circuit incorporated in the judging circuit 31 multiplies thus determined two differences by 3 and 5, for example, and then the differences are determined thus predicting the time when the rotational speed of the motor 8 exceeds a target speed. The judging circuit 31 produces a signal at the predicted time and turns a switch 32 to a steady feedback characteristic 36. By such arrangement, overshoot is avoided and the drum motor rises quickly and reliably.

Filed: 1984-01-17
Abstract: PURPOSE:To increase the effective memory capacity of a disk device and also to improve the using efficiency of the disk device, by providing both the alternate link information and the delayed alternate link information and therefore attaining the effective use of both an alternate track and an alternate sector. CONSTITUTION:When a magnetic disk device DKU11 is newly assembled, the alternate link information on a defective sector and its alternate sector is recorded to a related sector or track. The alternate link information is stored in a RAMII8 when the DKU11 is connected to a magnetic disk controller DKC10. Thus the address of the alternate sector is read out of the RAMII8 when a write or read action instruction is delivered from a HOST12 as long as the address of the defective sector is designated. Then the address of the alternate sector is designated to the DKU11 to perform writing or reading. In case another defect is produced with a delay, the processing is carried out with the delayed alternate link information. This system increases the effective memory capacity of the DKU11 with improvement of its using efficiency.

IPC: F02D13/02
Filed: 1983-01-19
Abstract: PURPOSE:To obtain a high engine output, by preventing backflow of exhaust gas and raising the intake efficiency at the time of engine operation when the opening of a throttle valve is small by employing such an arrangement that the valve closing timing of an intake valve or an exhaust valve is delayed at the time of high-speed operation of the engine while it is advanced at the time of low-speed operation of the engine. CONSTITUTION:A cam shaft is formed with a pair of cams having different profiles so that the valve closing timing of an intake valve on an exhaust valve is controlled by shifting a rocker arm along the axis of a rocker shaft by hydraulic force and thereby selecting a cam that operates effectively. Here, the valve closing timing is delayed at the time of high-speed operation of an engine while it is advanced at the time of low-speed operation of the engine. At the time of high-speed operation of the engine, the engine output is increased by raising the intake efficiency of the quantity of intake air. At the time of low-speed operation of the engine, on the other hand, the engine output is kept high by preventing back-flow of exhaust gas when the opening of a throttle valve is small, and thus also raising the intake efficiency of intake air.
